Hello all (I have also posted this to the SBIG forum and to SBIG Tech Support.

Almost without fail now, I get these highly focussed straight lines in my images...always at the edges.

When bright stars are nearby, I also get this:

I am pretty sure its coming off the AOL glass, and if it is an external reflection, I have tried masking around the outside of the AOL...to no avail.

Can I ask..anyone else seeing this or have an ideas as to how I can eliminate them? They are really tough to process out.

cheers
Martin
